LOW VOLTAGE VERSATILE

TELEPHONE TRANSMISSION

CIRCUIT WITH DIALLER

INTERFACE

SOP-14

DESCRIPTION

The UTC TEA1110A is a versatile telephone transmission circuit

providing full speech and line interface functions in electronic

telephone sets. This device works at a line voltage which can be as

low as 1.6V DC (with reduced performance) to enable parallel

connection of telephone sets. It also realizes electronic switching

between speeches and dialling.

DIP-14

The UTC TEA1110A is ideal for applications, such as line

powered telephone sets, cordless telephones, and fax machines,

answering machines.

FEATURES

Low DC line voltage; operates down to 1.6V (excluding voltage

drop over external polarity guard)

* Voltage regulator with adjustable DC voltage

* Provides a supply for external circuits

Symmetrical high impedance inputs (64kΩ) for dynamic, magnetic

or piezo-electric microphones

Asymmetrical high impedance input (32kΩ) for electric

microphones

* DTMF input with confidence tone

MUTE input for pulse or DTMF dialling

Receiving amplifier for dynamic, magnetic or piezo-electric

earpieces

AGC line loss compensation for microphone and earpiece

amplifiers.
